摘　　要：用半变异函数法、关联维法和三棱柱法对新疆东准噶尔金、银贵金属成矿区内卡拉麦里一带Au、As原生晕数据的空间结构性进行了研究 ,结果显示 ,Au、As元素在不同方向上的分维值变化情况与区域上的构造控矿特征相吻合 ;就区域上而言 ,As比Au的空间分布更复杂些。此外 ,对三种分维计算方法各自的优、缺点和实用性进行了探讨 。This paper deals with the spatial structure of Au and As geochemical primary halo data in the Kalamaili zone by using the semivariogram method, correction dimension method and triangular prism method. The results show that the magnitude of fractal dimension in different directions is consistent with the fact that NW trending faults control the formation of Au deposits in this zone. The spatial distribution of As is more complex than that of Au. Moreover, the paper analyzes the advantages and availability of the three methods respectively, and points out the implications of fractal structure of geochemical landscapes.
